Another object of the invention is the provision of a mop which canreadily be used in corners, in confined places, and under objects havinga minimum of vertical clearance.

Another object of the invention is the provision of a mop having itshead readily removable in order that it may be replaced, washed ordrycleaned at desired intervals.

Another object of the invention is the provision of a mop having areadily removable handle which facilitates its being shipped and stored.

Another object of the invention is the provision of a mop which has mostof its metallic parts shielded by fabric, thereby reducing to a minimumthe probability of marring the furniture when used by a carelessoperator.

The objects abovementioned and other advantages of our invention will bemore readily understood after a careful examination of the followingdescription wherein reference is made to the accompanying drawing inwhich:

Fig. 1 is a top plan view of a mop embodying our invention with portionsbroken away to more clearly illustrate the relation of parts.

Fig. 2 is a second top plan view showing the means of securing the mophead to the frame.

Fig. 3 is a sectional view on line 33 of Fig. 1.

Fig. 4 is a sectional view on line 44. of Fig. 1.

Referring more particularly to the drawing:

The device embodying our invention consists of the mop head '7, which isadapted to be mounted on a conventional handle 8 by the removable andadjustable means hereinafter more fully described. The head 7 consistsof a sheath 9, which is preferably made of a durable fabric materialsuch as canvas or duck. To the underside of the sheath 9 is secured, bymeans of stitching or other suitable means, the thrums or dustcollecting elements 10. The cover 11 of the sheath 9 has a substantiallyrectangular centrally disposed cut-away section 12 and a radiallydisposed slit 13, the latter being adapted to be closed by lacing or aconventional closure element 14, commonly known as a zipper.

A wire frame 15 is secured to the base plate 16, preferably by rollingunder the edges 1'7, although it may be attached with equal advantage bymeans of welding or sweating. The frame 15 is adapted to fit into thesheath 9 and serves as a support or mounting for the mop head 7.

Mounted on the base plate 16, by means of the centrally disposed bolt18, is an axially rotatable plate 19, which has two upturned edges 20with transverse openings therethrough adapted to engage the springfingers 21, which extend from the ferrule 22 secured to the end of thehandle 8. The rotatable plate 19 has a multiplicity of equally spacedapart vertical apertures 23 adapted to engage a like number of equallyspaced apart stops 24 positioned on the base plate 16. A coil spring 25is carried on the bolt 18 between the nut 26 and the rotatable plate 19and is adapted to normally urge the plate 19 against the base plate 16.

To assemble our mop, we first insert the bolt 18 through the plates 16and 19 and secure the spring 25 in place by the nut 26. The springfingers 21 of the handle 8 are then caused to engage the transverseopenings in the upturned edges 20 of the rotatable plate 19, after whichthe wire frame 15 is inserted between the layers comprising the sheath 9in such manner that the plates 16 and 19 are exposed through the cutawayportion 12. The slit 13 is closed by the closure element 14 and the mopis ready to be used.

If it is desired to use the mop in a narrow space, the handle 8 is swungto the position indicated in Fig. 2 for obvious reasons. If, on theother hand, a wide surface is to be mopped, the handle 8 is placed, withreference to the head 7, in the position as indicated in Fig. 1 forequally obvious reasons. To rotate the head 7 about the axis of thehandle 8, it is simply necessary to place the mop on the floor and placethe foot on the head 7 and pull up on the handle 8 until the spring 25has been compressed sufficiently to allow the stops 24 to disengage theopenings 23. The head may also be rotated by grasping the head in onehand and the handle in the other hand and pulling them apart until thespring 25 is sufficiently compressed to allow the stops 24 to disengagethe openings 23.

It is obvious that because of the manner in which our improved mop isconstructed that our device can easily be forced under articles offurniture which have a very low vertical clearance.

It is also obvious that the head 7 can readily be removed and washed ordry-cleaned inasmuch as it is entirely made of fabric.

It is also obvious that our improved mop can be used with equal ease onfloors, walls and ceilings simply by moving the handle to the positionmost adaptable to the work to be done.

It is also obvious that because the sheath 9 covers practically all ofthe metallic parts of our improved mop, very little danger would beencountered in scratching or marring the furniture.

Having described our invention, what we claim and desire to secure byLetters Patent is:

In a device of the character described having a handle and a frame, arotatable mounting for said handle comprising in combination two plates,an axially disposed slidable pivot extending through said plates, meansat each end of said slidable pivot to limit its displacement, means forattaching one of said plates to said frame, means for attaching theother said plate to said handle, said last named means consisting of twooppositely disposed upstanding elements having hori-f angularly disposedarms carried at one end of said handle and so arranged that the axis ofsaid arms intersects, at right angles, the axis ot'the aforesaidslidable pivot, one or more male elements carried by one of said platesadapted to engage one or more female elements carried by the other saidplate to lock said plates against individual rotation and spring meansfor normally urging said locking elements into co-operation. v.
